Crime Scene Investigation at Home of 'CSI' Star

Gary Dourdan of "CSI" fame was the alleged victim of domestic violence Tuesday afternoon, and his much smaller girlfriend was cuffed and taken into custody ... law enforcement sources tell TMZ.

Cops were called to a Venice, CA home in the early afternoon. We're told when they arrived they found Dourdan scratched up. They arrested Maria Asis del Alamo where she was taken to the station and booked on misdemeanor domestic battery.
